Find LCM of 817,540,546,330,221 with Prime Factorization
2 | 817, 540, 546, 330, 221 |
3 | 817, 270, 273, 165, 221 |
5 | 817, 90, 91, 55, 221 |
13 | 817, 18, 91, 11, 221 |
817, 18, 7, 11, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 817 x 18 x 7 x 11 x 17 = 7507560060
Therefore, the lowest common multiple of 817,540,546,330,221 is 7507560060.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
817 x 540 x 546 x 330 x 221 = 17567690540400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
817 : 1, 19, 43, 817
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,540,546,330,221, is 1.
Now, the common factors can be found like this.
817:19x 43
540:2x 2x 3x 3x 3x 5
546:2x 3x 7x 13
330:2x 3x 5x 11
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5x 13 = 2340
Therefore, the value for common factors is 2340.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 17567690540400/(1x2340)
LCM = 17567690540400/2340
LCM = 7507560060
Thus, we can understand that the LCM of 817,540,546,330,221 is 7507560060.
